How can a Ruminant
digest these things? Through the process of rumination
Eating rapidly, regurgitating and
masticating their feed. (Chewing their cud)
With specialized structures in their
stomach
Ruminants have microorganisms living inthem that break down
cellulose for them
and make those nutrients absorbable.

Rumen
Large fermentation vat
Microorganisms break down cellulose
Creates lost of gases (methane)
Ruminants have to be able to eructate
(belch)
Some nutrients are absorbed
Roughages are reduced in size
